Returning characters & costumes – limited time or not?

A lot of you have been asking if the returning characters & costumes that have appeared in our games are only available for a limited time. From what I’ve been told they are linked to the districts you’ve unlocked so should not be limited time. However I realise a few of the costumes say they are limited time, ie Gay Couple Stewie. I’m thinking this might just be the written description from their first release in the game which would have been during an event.

However to put minds at ease I’ve asked support to confirm again that these are here to stay and I’ll post their response once they come back to me.
